Strace as root

There is new evidence, suggesting that with MESA_LOADER_DRIVER_OVERRIDE=iris
the driver is actually loaded, but only if run by root (as seen in the attached
files). If run as non-root, however, mesa attempts (and fails) to load i965
rather than iris. There might be a permission/caps problem.
